I actually drove that one to work tonight. It still has the cleanest oil changes out of all my cars.
Dropping the sump plate does sound like a good idea. Residue will get trapped there and with the plate off, there is access to much of the internal engine for inspection and cleaning.
My biggest concern with the engines specifically in the 2000 model year S models is cracked heads. I have had one and read and heard of it happening many more times to that particular year than any other. Good news that Sunset pressure tested the cooling system and didn't find a leak.
If it was my car:
Drop the sump, clean what can be cleaned until spotless (including removing and reinstalling the plastics).
Run it for a short time with a good, but less expensive oil (Rotella T6 5W-40).
Check the oil for intermix at the filter.
Clean? Run it twice as long and check it again. Repeat until confident.
Intermix? Note the extent - keep the sample/take a pic. Drain and refill. Run check, compare.
